In the early morning hours of Sept. 24, 2016, Acosta entered the Fullerton home of 39-year-old Jennifer Goodwill-Yost and her husband 34-year-old Christopher Yost, where the victims’ friend, 28-year-old Arthur William Boucher, was also staying the night.

Felix is accused of helping Acosta acquire a shotgun and waiting in a truck outside the home.

Acosta entered the living room and shot Boucher in the head as the victim slept on the couch.

The defendant then went to the master bedroom and shot Goodwill-Yost in the face.

Yost awoke and Acosta shot the victim in the head as he was fleeing outside.

Felix is accused of driving Acosta to Felix’s home where they attempted to destroy evidence.

Minor children discovered the bodies in the morning and called the Fullerton Police Department (FPD), who investigated this case.

FPD located and arrested Felix at his home in Sun Valley and Acosta in his barracks at Fort Irwin.
